Title: Device for geometrically compensating turbulence of magnetic susceptibility in rf spectrometer
Inventor: HAWAADO DEE HIRU
IPC: G01R33/34
Filed: 1991-11-01
Abstract: PURPOSE: To reduce disturbance of magnetism due to the inherent structure by varying the area of a conductive material having a predetermined thickness, as a function of the axial direction, thereby distributing a field in the radial and axial directions. CONSTITUTION: It the thickness of a conductor is constant at typical parts 56, 58, 60 (total area of coil part surrounded by dashed lines) of a saddle coil having a constant microwidth, that material (sample) is rotated. By so doing, the area is averaged, regardless of the axial direction, and a constant mean magnetization rate is distributed along the axial direction and the axial forward end part of the coil serves to remove magnetic disturbance from the high sensitivity volume of the coil. When the total area of the coil is equalized per unit length in the axial direction, the magnetization rate is distributed uniformly in the axial direction. Consequently, the combined results is applicable to a case, where a uniform sample space is required along the axial direction.  When the dependence of the magnetization rate on the axial direction is set as a function of the axial direction, a compensation gradient is provided and a constant combined field is formed in the axial direction.

Title: Correlation pulse generating circuit
Inventor: UCHIDA YOSHITAKA
IPC: H04B1/707
Filed: 1989-12-01
Abstract: PURPOSE:To attain sure data demodulation even when an output signal level of a correlation device is fluctuated by retarding an output of an absolute value detection circuit, comparing the retarded signal with a threshold level signal and generating a correlation pulse. CONSTITUTION:A delay circuit 11 uses a sampling signal (b) as a clock, an output (e) selected from an output (c) of an A/D conversion circuit 2 or an inversion circuit output (d) obtained by a selection circuit 4 is delayed by nearly one period of a clear signal (g). A comparator 8 compares an output (m) of the circuit 11 with a threshold level signal (j) of a threshold level setting circuit 7 and when the output (m) larger than the signal (j) is inputted, a correlation pulse (k) is outputted. Moreover, the most significant bit (f) of the output (C) is inputted to a delay circuit 12 and the polarity of correlation spike is discriminated by the outputted most significant bit (n). Thus, since the polarity is discriminated based on the amplitude information of the current correlation spike, even when the output signal level of the correlation device is fluctuated, the data is surely demodulated.
